Trend Crush: Denim On Denim

It’s taken me a long time to admit this, but I’m dying to try the denim on denim trend. I think that if done the right way, it looks really great.
I think the reason it took me so long to come to terms with this trend and the fact that I actually like it is because when I first sported this look in elementary school, it looked something like this.
But now I’m ready to give this look a go for the fall. I’m thinking something along the lines of what Jordan from Oh Happy Day has set up here.
What do you think? Demin on demin - yay or nay?
